The more meat you eat, the more weight you will gain over time, according to a new study by British researchers of the Imperial College in London.
Nearly 400,000 men and women from 10 European countries took part in the study. Researchers found that meat lovers gained more weight over a five-year period than those who ate less meat.
Interestingly, the strongest association with weight gain was poultry. Next was processed meats and red meat.
Over a five-year follow-up, while both men and women both gained about a pound a year on average, women gained less weight overall.
Heavy meat-eating could be part of an overall unhealthy diet or unhealthy lifestyle, the team of researchers noted.
"More importantly," they add, "our results do not support that a high-protein diet prevents obesity or promotes long-term weight loss, contrary to what has been advocated."
The results of the study were published in the American Journal of Clinical Nutrition.
